A trapezoidal channel of 2.0 m bed width, 2.0 m water depth, and 1 : 1 side slope carries a discharge of 20.0
/s. The channel has a bed slope of 8 cm/km and a Chezy roughness coefficient of 60 (metric). To what rate does the depth of flow change with distance?

A wide rectangular channel carries a specific discharge of 6.0
 /s with a bed slope of 12 cm/km. The depth of flow is 1.2 m and the Manning roughness coefficient is 0.017 (metric). Find the rate at which the depth changes with distance
